fwn/.11541111544 /l WITNESSES ATToRNEY or' combustion assino through the dam Jer when the latter is opened or being retained in the Hue; and it is obvious that articles and receptacles ot proper size may be stood upon the upper end of the flue or placed upon the damper plate and heated or perhaps cooked thereon. It a group ot perhaps three or four of these hues were employed, it is possible that a good sized re-` ceptacle might be placed ov i the upper ends of all of them, and food' therein cooked from the combined heat from the several burners. lf the valve V be employed the iiow of gas may be regulated at this point instead of or in addition to its regulation at the key of the burner tip or bracket. y

Connected with the coupling C is a hose pipe 10 of sufficient length to lead i'rom the nearest available faucet F to this device, and the hose is attached to an inlet pipe 11 which need not be larger than one-quarter inch with a heater of ordinary size. This inlet pipe enters shell 2 at a point 12 which is by preference somewhere near the lower end of the first jacket, so that the cold water is led into this jacket immediately around its burner and receives the greatest amount of heat from the latter. Therein "the water rises until it overflows at the point 13, and iiows then through a pipe 14 to a low point 15 in the next jacket where again it receives heat from the burner therein. Within this jacket it rises again, and soy on, throughout the several flues and jackets. The overiiow is at 16 to an outlet pipe 17 which need not have a faucet, but may have one it' desired.1`hus the course of the water is from its inlet 11 where it is cold, to the lower end of the first jacket and upward therein, thence out of this jacket at 13 to a low point- 15 in the next jacket, thence upward within this jacketY to a point 16 and out at the outlet 17; and the result is that hot or warm water may always be drawn from the point 17 because it has been warmed by at least two burners, and when it is withdrawn from a second jacket, water that has been preliminarily heated in the first jacket flows into the second jacket to replace that drawn out. Hence if the burners are turned on'so that they emit but a small blaze, warm water may always be drawn at the outlet 17; and if they are turned up so that considerablev heat is generated, hot water may always be drawn, but

in no event will cold water flow out the outlet 17 if the burners are lighted at all. It is quite obvious that, as above suggested, with more than two flues the eiliciency of the deheadset vice would be increased and its possibilities amplified. We do not wish lto be limited in this respect, nor as to the sizes, proportions,

-materials and exact details of construction.

Any suitable means may be provided for supporting this heater, and as shown herein we have employed a stand consisting of a base 20 whose standards 21 are connected with the spiders 7, the latter in turn supporting the gas connections andflues and water connections. For bracingthe parts it might be wise to employ a `member best seen in Fig. 3, and'which maybe cast or stamped in'two parts and linally connected by rivets or bolts 22. The member includes large'l'oops 23 which embrace the flues 1, and a small central loop 24 which embraces the pipe between thev valve V and miXer M, and by tightening up on the bolt 22 the several loops will` be caused to clamp the parts which they embrace. ln a very large sized Vdevice* this bracingv Vmember might be repeated or duplicated above the valve V, but we do not consider it'necessary to show the same. j

What is claimed as new is 1. 1n a water heater of the class described,

the combination with a pair of upright Hues, water jackets around them, means forcirculating water through the jackets, and

Vmeans for controlling its iowg-of gas burners disposed respectively in the lowerfends rlues, a stand supporting said spiders, and

a clamping member having large loopssurrounding the iiues and a smaller interposed loop surroundingrthe gas supply pipe, for the purpose set forth.

2. ln a water heater of the class described, the combination with a pair of upright ues, each surrounded by a water jacket, means for admitting cold water to the lower end of one flue, conducting it from the high end thereof to the lower end of the next flue, and permitting it to flow out of the high end of the last-named tlue, and means for controlling the flow of water; of gas burners disposed respectively in the lower ends of the iiues, means for supplying gas thereto and controlling its flow, a spider in the lower end of each' flue through which the burner-pipe passes, a stand for support BERT HART.
